As a fan of pretty much anything that shoots a projectile, I found this interesting. A Nerf Sentry gun is nothing new. Ever since Hasbro came out with the N-Strike Vulcan EBF-25 Nerf fans and college students have been mounting them onto computer controlled gimbles.
The truly outstanding aspect of this build, is the targeting and IFF recognition. You can program the computer to recognize a design and not shoot at it. So you can dress up as Colonial Marines and pretend all your enemies are acid blooded aliens. Very clever indeed. Now mount a M60 or a Shrike to it haha.
A big thanks to Whale Oil for sending this in to us.
